It's hard not to get a slight sense of vertigo from these stereographic projections by Dutch photographer Wouter van Buuren. Each one was taken from a very high point across the Netherlands, China, and New York City.

If you look closely, you'll notice that they aren't single photos like you'd get from a 360-degree or fish-eye lens. In fact, each shot has been cobbled together from numerous smaller photos to create what look like miniature planets from the two-dimensional landscapes.
